1997 Burb, Drivers side barn door does not open

I know that there has been a lot of write ups regarding the rear doors not opening. The 1997 has one latch on the left door. it is between the two doors. That latch is connected to two rods that go the the top and bottom locking mechanism. On my vehicle the lower rod is not connected to anything, see pic. Is there something missing? How do I open this door so I can replace the parts?

I have drawn the arrow to the hook of the lower rod. I am assuming that something broke. Is the rod supposed to connect to an arm that may have broke off the part that is circled in red?

I've got a 98 with barn doors. If I get time in the next few days, i'll take the panel off and see what it looks like. I go to work when it's dark and unfortunately get home when it's dark so it may have to wait until this weekend... Greg
